The Aircraft of World War I

"A great deal of an aeroplane could be holed without affecting its ability to fly. Wings and fuselage could be—and often were—pierced in 50 places, missing the occupants by inches (blissfully unaware of how close it had come until they returned to base). Then the sailmaker would carefully cover each hole with a square inch of Irish linen frayed at the edges and with a brushful of dope make our aircraft 'serviceable' again within an hour." Lewis, Cecil. Farewell to Wings
